Hi Clark, there are a number of reasons why this would be happening. Could you tell me more about what program you're trying to flash? Are you sure your compiling for the right target? Has this program worked before? And if so, what has changed?

Thanks, Brian

Thank you answer .

I have forgotten to write The CPU of STM32 becomes hot.

my program is working before does not work. first does not work program

  1. include "mbed.h"

PwmOut k(D15); Serial pc(USBTX, USBRX); DigitalOut myled(LED1); char i; long long a; int j; int main() { pc.printf("START"); k.period_ms (15);

k.pulsewidth_us (1000); wait(3.0);

k.pulsewidth_us (1200); wait(10); a=1000; while(1)

{ i=pc.getc();

if(i=='1'){ a+=1; i=0; pc.printf("up"); }

else if(i=='2') {a=a-1; i=0; pc.printf("down"); } else if(i=='3') {a=1000; i=0; pc.printf("STOP"); } else { pc.printf("no"); } k.pulsewidth_us (a); } }

second, I try easy program. But, don't flash LED.

  1. include "mbed.h"

DigitalOut led (LED1); int main() { while(1) { led=1; wait(1.0); led=0; wait(1.0); } }

Hi Clark,

If the blink example doesn't work than that's not a good sign :(

Are you able to program the board with the blinky example? Or are you getting the FAIL.TXT?

Thanks, Brian

Thank you comment, I can program blinky example, But,now I am not getting the FAIL.txt. STM32 is hot now. and the board not connect anything without USBminiB.

Ok, it sounds like your board may be having hardware issues. The last thing I would try to recover would be to reflash the ST-Link firmware, which you can get from here: http://www.st.com/content/st_com/en/products/embedded-software/development-tool-software/stsw-link007.html

But other than that I'm not really sure of the next steps. You could always contact ST about it but it may be easier to just try a different board if you have it.
